基于WRC-19 1.13议题研究框架和国内6 GHz以上IMT-2020(5G)候选频段的兼容性分析要求,针对24.65~25.25 GHz频段IMT-2020(5G)系统对卫星广播系统的干扰进行研究。采用蒙特卡洛的仿真方法,比较了静止轨道卫星经度分别在东经59°、85°、113°时,IMT-2020(5G)系统基站对卫星广播系统上行馈线链路的集总干扰情况。通过仿真分析,评估了5G系统对不同轨位卫星两类载波的集总干扰水平。研究结果表明,在该频段,IMT-2020(5G)系统不会对卫星广播系统产生有害干扰,相关研究结果可为未来毫米波频段IMT-2020(5G)系统频率规划以及保护卫星广播系统提供技术依据。
Based on the Agenda Item 1.13 of WRC-19 and requirements for domestic compatibility analysis of 5G candidate frequency bands above 6 GHz
the interference from IMT-2020 system (5G) to broadcasting satellite service system in 24.65~25.25 GHz band was studied.The Monte Carlo simulation method was used to assess the aggregate interference from IMT base station (BS) to the up-link of feeder link of broadcasting satellite where the geostationary orbit satellite at 59℃
85℃ and 113℃ longitude.The aggregate interference level from 5G system to the two kinds of carriers of the satellite system with different orbits was evaluated via simulation analysis.Research results show that the IMT-2020 (5G) system will not cause harmful interference for broadcasting satellite services system.The results can provide technology basis for future planning of IMT-2020 (5G) system in millimeter wave and protecting of broadcasting satellite system.
